3D lines

drawing tool this geometry shape is drawn using the 3d line tool it is mainly used for outlining areas drawing process select a class move along the line or edge and place points where you want to have control points the points will be placed at the lowest point in the point cloud at that location continue placing points until you feel done with the object create from a prelabel select a class shift+click on a prelabel to apply the selected class transformation controls adjust use the 3d docid\ ai1c20i3hou bexm8ffmx to adjust the placement of the line point to change the entire line, press shift before moving the controls extend the line you can extend a line from the start or end with keyboard shortcuts press 0 to extend the line from the end or shift+0 to extend the line from the beginning zoom to selected zoom to selected to quickly review the points along a line by pressing k select point in 2d miniature image you can select projected 3d line points in the 2d miniature image docid\ hngmpfpjhtmacdfuwwe8m docid\ budtv3ll0y3hhqyk8qxgl step between points step between points using alt+n and alt+p reverse direction you can reverse the line direction by clicking on the 3d lane with the right mouse button and selecting "reverse direction " see docid\ vg0rqvtpdkrett4osvwch for how to view lane direction indicators you can add a custom shortcut to reverse the direction of the selected 3d line see docid\ zeohmsoo kfy qzqnmny2 for how to add a custom keybinding automatically close lines 3d lines can be configured to automatically be closed this way the last node will always connect to the first and is visualized while drawing related content the docid\ t7pvih7 6 q3nbueccdgf feature is a way to automatically generate 3d lines based on other lines, such as lane connections and centerlines docid 9y0ax8qabl5ceikmqxrde shares insights on how to transform one node or the entire shape at a time find out how you can docid\ umf1ixrqo2cpgel0yqttl on 3d lines and lanes, allowing you to adjust or remove the nodes
